I have been very interested to read all the different ways folks on the 100+ Board find to move their bodies. Does it seem to you like most exercise fits into one of three categories: strength, cardio, and flexibility? (Obviously some kinds of work-outs incorporate more than one of those categories). I personally think of core strength training (this explains that http://www.mayoclinic.com/health/core-exercises/SM00071) as different than standard strength training.
I am currently only walking ---- I don't even stretch before or after! How do you move your body? Are you sampling from all three different menus? What keeps you going?
